Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1-3 This patent provides a technical solution: a maintenance frame for a bridge crane that is easy to move, including a maintenance frame body 1 and a lift 2, a fixing plate 3 is installed on the upper wall of the lift 2, and the maintenance frame body 1 is installed on the upper wall of the fixing plate 3;

[0022] Positioning mechanisms 4 are inserted and installed on the left and right sides of the maintenance frame body 1, and the positioning mechanisms 4 can be set up on the running track of the external bridge crane;

[0023] The maintenance frame body 1 can be raised to the level with the bridge crane by the lift 2, and then the maintenance frame body 1 can be installed on the track of the bridge crane by the positioning mechanism 4. The maintenance frame body 1 moves on the track by the positioning mechanism 4. Compared with the method of supporting by the ground, the device is more convenient when adjusting the position and will not be blocked by the equipment on the ground. At the same time, the maintenance frame body 1 can be connected to the bridge crane by the sliding ring 17, so that it can change its position together with the bridge crane, which is very convenient.

[0024] The positioning mechanism 4 includes an upper support plate 41, an electric control push rod 42, a main rotating wheel 43, a support rod 44 and an auxiliary rotating wheel 45. A slide groove 5 is provided on the side wall of the maintenance frame body 1. The electric control push rod 42 is inserted and installed in the slide groove 5. The electric control push rod 42 is electrically connected to an external power supply. The upper support plate 41 is inserted into the slide groove 5 and connected to the output end of the electric control push rod 42. The lower wall of the upper support plate 41 is installed with a main rotating wheel 43. One end of the support rod 44 is installed on the side wall of the maintenance frame body 1. The other end of the support rod 44 is installed with an auxiliary rotating wheel 45. The main rotating wheel 43 and the auxiliary rotating wheel 45 can clamp the external bridge crane running track.

[0025] When the maintenance frame body 1 is raised to be flush with the bridge crane by the action of the elevator 2, the electric control push rod 42 can be controlled to retract, and then the elevator 2 continues to rise until its track is located between the upper support plate 41 and the auxiliary rotating wheel 45 and then stops. Then the electric control push rod 42 is controlled to be pushed out so that the main rotating wheel 43 is in contact with the upper wall of the track, and the track is clamped by the main rotating wheel 43 and the auxiliary rotating wheel 45, so that the maintenance frame body 1 is hung on the track.

[0026] Specifically, a connecting frame 6 is welded on the upper wall of the fixing plate 3, and there are four connecting frames 6. A positioning pin 7 is inserted and installed in the side wall of the connecting frame 6. The four connecting frames 6 are respectively located at the four corners of the maintenance frame body 1. The four corners of the maintenance frame body 1 are provided with connecting holes 8, and the positioning pin 7 can be inserted and installed in the connecting holes 8;

[0027] After the maintenance frame body 1 is hung on the track, the positioning pin 7 needs to be pulled out from the connection hole 8 to disconnect the lifter 2 from the maintenance frame body 1 to prevent the lifter 2 from affecting the movement of the maintenance frame body 1 .

[0028] Specifically, a clearance groove 9 is formed on the side wall of the maintenance frame body 1, and an interception plate 10 is hingedly connected to the side wall of the maintenance frame body 1, and the interception plate 10 can be inserted into the clearance groove 9;

[0029] The intercepting plate 10 can be regarded as a door plate of the maintenance rack body 1 . By opening the intercepting plate 10 , it is convenient for workers to enter the maintenance rack body 1 .

[0030] Specifically, a mounting groove 11 is provided on the lower wall of the upper support plate 41, and positioning grooves 12 are provided on the left and right sides of the mounting groove 11. Bearings 13 are installed in the positioning grooves 12, and bosses 14 are installed on the left and right sides of the main rotating wheel 43. The bearings 13 are sleeved on the outer sides of the bosses 14, and the main rotating wheel 43 can pass through the upper wall of the upper support plate 41 through the mounting groove 11.

[0031] Specifically, the positioning pin 7 includes a pin body 71, a side plate 72, a slot 73 and a spring 74. The side wall of the pin body 71 is rotatably mounted with the side plate 72. There are two side plates 72. The side walls of the two side plates 72 are both provided with a slot 73. The two ends of the spring 74 are respectively inserted and mounted in the two slots 73.

[0032] After the positioning pin 7 is inserted into the connecting hole 8 , the side plates 72 on both sides of the pin body 71 will open under the action of the spring 74 to prevent the positioning pin 7 from falling out of the connecting hole 8 .

[0033] Specifically, fixed rods 15 are installed on both sides of the upper wall of the maintenance frame body 1, a cross bar 16 is installed between the two fixed rods 15, and a sliding ring 17 is sleeved on the outer side of the cross bar 16;

[0034] The maintenance frame body 1 can be connected to the bridge crane through the sliding ring 17, so that the maintenance frame body 1 can be moved by the bridge crane. In addition, the staff's protective rope can also be sleeved on the cross bar 16 to protect the staff.

[0035] Working principle: after the maintenance frame body 1 is raised to be flush with the bridge crane by the action of the lift 2, it can be retracted by controlling the electric control push rod 42, and then the lift 2 continues to rise until its track is located between the upper support plate 41 and the auxiliary rotating wheel 45 and then stops, and then the electric control push rod 42 is controlled to be pushed out so that the main rotating wheel 43 is in contact with the upper wall of the track, and the track is clamped by the main rotating wheel 43 and the auxiliary rotating wheel 45, so as to complete the hanging of the maintenance frame body 1 on the track, and then the positioning pin 7 is pulled out from the connecting hole 8 to disconnect the lift 2 from the maintenance frame body 1 to complete the installation of the maintenance frame body 1. At this time, the staff is located in the maintenance frame body 1 to repair the bridge crane.
